The fastest movers in the animal Kingdom.

1. Peregrine Falcon – The fastest animal on Earth, capable of reaching about 389 km/h (242 mph) in a hunting dive.

2. Cheetah – The fastest land animal, sprinting up to 98–112 km/h (61–70 mph) for short bursts lasting under 30 seconds.

3. Sailfish – Among the fastest fish, reaching speeds of around 70 to more than 100 km/h (43–62 mph) in short underwater bursts.

4. Gazelle – Agile and swift, a gazelle can run up to 80–90 km/h (50–56 mph) and maintain high speeds for longer distances.

5. Horse – A racehorse can reach 88 km/h (55 mph) at peak, while most horses gallop around 48 km/h (30 mph) in normal conditions.

6. Grizzly Bear – Surprisingly fast for its size, it can run up to 56 km/h (35 mph) over short distances.

7. Hyena – Built for endurance, a spotted hyena can run steadily at 60 km/h (37 mph) during long pursuits.

Allen bolts (Hex bolts) are tightened using a hex key (Allen key). For proper fastening, the key size must perfectly match the bolt head. Using the wrong size can round the head, damage the tool, and reduce tightening accuracy.

Key Points to Know:

Each Allen bolt has a specific internal hex dimension.

Always use the exact key size, especially in high-torque areas.

Avoid worn or rounded keys to maintain grip.

A correct fit ensures clean torque transfer and longer bolt life.

Professional Tip:
If a bolt head begins to round, stop immediately. Switch to a fresh, sharp hex key or use penetrating oil before re-tightening. Prevention is always easier than extraction.
